I purchased a new HP Desktop and installed the internal SSD from my old PC. The boot order in the BIOS doesn't list individual hard drives to boot from, so it always boots to the hard drive that came with the system and doesn't provide me with any other options to boot from the additional SSD. Windows recognizes it just fine but I cannot for the life of me figure out how to boot from it.

If your bios looks like the following (select boot option)

Possibly you need to enable legacy boot and disable secure boot before the disk drive becomes available.
You did not mention your previous system. Is the drive compatible? ie: was it formatted for MBR or GPT or was it controlled as IDE instead of AHCI?
What is it you are trying to do? Do you really want to boot from or just obtain files that are on it?
